View Product DetailsA comprehensive analysis of optical brightener additive science, carrier resin viscosity matching, and light scattering mitigation in polyolefin processing.
Transparent Brightening Polyethylene (PE) Masterbatch utilizes high-purity organic fluorescent optical brighteners (primarily bis-benzoxazole structures like OB and OB-1). These micro-molecules absorb invisible ultraviolet (UV) light energy in the 360–380 nm range and re-emit visible blue-violet light energy at 430–450 nm, counteracting the natural yellowish hue of polyolefin resins.
Polyethylene matrices (LDPE, LLDPE, HDPE) naturally contain semi-crystalline and amorphous phases that cause light scattering, resulting in haze. Our specialized brightening masterbatch acts as a physical nucleation assist and optical compensator, minimizing refractive index mismatches and elevating light transmittance up to 92.5% in thin film applications.
To prevent phase separation or surface blooming, our carrier resins (virgin LLDPE with MFI ranging from 4.0 to 20.0 g/10min) are custom-compounded to match your target processing polymer. This guarantees zero melt fracture, uniform dispersion, and consistent mechanical tensile properties during high-speed extrusion or injection molding.
Technical Insight for Buyers: Achieving maximum optical clarity requires balancing pigment loading and carrier Melt Flow Index (MFI). Excess brightener loading can lead to "optical saturation" and chalking/blooming over time. Partnering with an experienced manufacturer ensures precise additive ratios calibrated to your specific extrusion temperature profiles.

| Thermal Processing Stability | TGA Thermal Analysis | Up to 280°C – 300°C | Prevents thermal degradation during high-temperature injection molding. |
| Light Fastness Rating | ISO 105-B02 (Xenon Arc) | Grade 6 – Grade 7 | Resists UV degradation and yellowing in outdoor packaging applications. |
| Heavy Metal Compliance | ICP-OES / RoHS 3 Directive | Pb, Cd, Hg, Cr(VI) < 100 ppm | Complies with global food contact regulations and FDA standard 21 CFR. |
Our 6,000m² factory utilizes continuous twin-screw extrusion technology combined with online spectral color measurement to guarantee batch-to-batch repeatability.
Our manufacturing plant operates multiple co-rotating twin-screw compounding extruders equipped with high L/D ratios (44:1) and multi-stage vacuum degassing systems. This physical setup guarantees that active optical brighteners are uniformly dispersed at the sub-micron scale, preventing agglomeration, streaking, or pinhole defects during high-speed film blowing down to 10 microns.
Every production lot undergoes rigorous Quality Assurance testing. We measure Filter Pressure Value (FPV < 0.5 bar/g using standard EN 13900-5) to verify dispersion quality, alongside spectrophotometer color space analysis (CIE L*a*b* standard). This ensures that when you order "Cheap Transparent Brightening PE Masterbatch," you receive world-class performance without quality compromises.
Leverage Changzhou Jiazhou Plastic’s integrated raw material network, massive compounding scale, and localized supply chain resilience.
Located in Changzhou, Jiangsu Province, our factory benefits from direct proximity to China’s major petrochemical hubs (Sinopec, CNPC). Direct bulk purchasing of virgin LLDPE/LDPE carrier resins cuts core material procurement costs by 12–15% compared to Western compounders.
Operating 6,000m² of automated compounding space allows us to minimize energy consumption per metric ton. These production efficiencies are directly passed on to global buyers seeking affordable, highly transparent optical brightening masterbatches.
With fast access to Shanghai and Ningbo deep-water ports, we ensure rapid export container loading. Standard order fulfillment times are kept under 15 calendar days, reducing safety stock buffer costs for overseas distributors.
Analyzing how circular economy regulations, post-consumer recyclate (PCR) upcycling, and global compliance standards drive masterbatch innovation.
As global brand owners mandate 30%+ recycled plastic content in packaging, Post-Consumer Recycled (PCR) PE resins suffer from heat history degradation and yellowing. Transparent Brightening Masterbatch neutralizes unwanted yellow-brown tints, elevating low-grade recycled resins into premium visual clear packaging.
Global regulatory pressure mandates clean formulations free of hazardous phthalates, heavy metals, and migrating VOCs. Our transparent brightening formulations comply with EU REACH Annex XVII, RoHS 3.0, and FDA 21 CFR 177.1520 regulations for safe food contact packaging.
Modern packaging converters are down-gauging blown films to reduce plastic consumption. This requires masterbatch additions with ultra-fine particle dispersion (D50 < 2 µm) to prevent bubble tears, pinholes, and gauge variations during high-speed extrusion lines.
Engineered for high performance across film blowing, injection molding, sheet extrusion, and blow-molded hollow containers.
Used in high-clarity food shrink wraps, agricultural greenhouse covers, shopping bags, and stretch films. Delivers crystal clarity and eliminates yellowish haziness under natural daylight.
Ideal for clear plastic storage boxes, food containers, caps, closures, and household items. Increases surface gloss, aesthetic radiance, and consumer visual appeal.
Applied in PE profile extrusion, translucent sheets, protection films, and pipe jacket layers requiring surface brightness, anti-yellowing performance, and uniform color shade.
Provides milk bottles, cosmetic containers, and chemical carboys with clean white-transparent aesthetics, hiding regrind blemishes without sacrificing plastic translucency.
A step-by-step framework for international B2B buyers to optimize Total Cost of Ownership (TCO) and ensure smooth custom development.
Buyers specify target processing parameters (extrusion vs injection), base resin melt index, let-down ratio (LDR), thermal stability targets, and food-contact compliance needs.
Our R&D laboratory formulates custom pilot batches (1–5 kg) within 48 hours. Spectrophotometer analysis and cast-film extrusion tests confirm optical clarity before full-scale trial.
Once sample validation is approved, production scales seamlessly to 20-ton container loads with moisture-proof 25kg moisture-barrier bags, dispatched directly to your designated seaport.
Detailed technical answers to common engineering, formulation, and procurement questions from plastic processing experts.
The standard let-down ratio (LDR) ranges between 1.0% and 3.0% (1:100 to 3:100 weight ratio) depending on the virgin resin purity, film thickness, and proportion of recycled PCR polymer used. For virgin LDPE/LLDPE blown film, an addition rate of 1.0% to 1.5% usually yields optimal transparency and blue-phase optical brightness without surface blooming.
No. Because our carrier resin is composed of high-purity virgin LLDPE and active additives are fully dispersed down to sub-micron particle sizes, our transparent brightening masterbatch does not migrate to the surface or interfere with corona treatment, surface tension, gravure printing inks, or heat sealing strength.
Absolutely. In fact, PCR and industrial regrind plastics represent one of the primary application scenarios for transparent brightening masterbatches. Recycled PE often suffers from yellowing caused by multiple thermal processing histories. Adding 1.5% to 2.5% brightening masterbatch neutralizes yellowish undertones, restoring a clean, bluish-white appearance that resembles prime virgin resin.
Our brightening masterbatch utilizes heat-stabilized optical brightener grades (such as OB-1 and modified bis-benzoxazoles) capable of enduring continuous processing temperatures up to 280°C (and brief peaks of 300°C) without molecular breakdown, color fading, or thermal gas evolution.
Yes, specific grades within our transparent brightening PE masterbatch series are formulated using raw materials compliant with FDA 21 CFR 177.1520 and EU Regulation No 10/2011. Heavy metal content (Lead, Cadmium, Mercury, Hexavalent Chromium) is strictly below 100 ppm, satisfying RoHS 3 and REACH requirements.
As a direct manufacturer with 16 years of compounding expertise and 6,000m² of plant space, we bypass regional trading markups. Our direct integration with upstream domestic petrochemical suppliers gives us a structural cost advantage, allowing us to supply premium-grade brightening masterbatches at highly competitive wholesale rates.
